Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
RRA08202502
A small number of Rolls-Royce Cullinan (RR31) vehicles have been identified as having a potential issue concerning the key recognition. Due to a software error, the vehicle key may not be reliably recognized inside the trunk (boot) of the vehicle. This may potentially allow the vehicle to be locked while the key is in the trunk.
RRA01202501
The tread plate should be gently pried up using an appropriate plastic wedge tool, and then the ribbon cable connector released.
RRA12202405
A small number of Rolls-Royce Phantom (RRll/RR12), Ghost (RR21/RR22), Spectre (RR25), and Cullinan (RR31) vehicles have been identified as having a potential software issue concerning the personal e-SI M profile. As a result, vehicle telephone and Wireless Area Network (WLAN) hotspot functions via the personal e-SIM may operate with a delay or not operate sporadically. The problem has been rectified with vehicle software version 24-77-540 (RR21-24-11-540 for RR21/RR22, RR25 and SlSA-24-11-540 for RR11/RR12, RR31), which is included in 1ST A version 4.50.4x.
RRA04202404
A small number of Rolls-Royce Cullinan (RR31) vehicles have been identified as having a potential issue concerning the rear axle differential which may have the internal circlips installed incorrectly.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
